You want to add HP edge switches to a company's Cisco network. Distribution Cisco
switches are set as the Rapid PVST+ root and secondary root. You connect HP A-Series
switches that are running their factory default configuration to the two Cisco distribution
switches. What will happen?
A. If you connect the edge switch with a redundant link to both distribution switches, you
create a loop and a broadcast storm on the Cisco network.
B. Cisco distribution switches send tagged PVST+ BPDUs to the HP switch. Because
802.1q is not yet configured on HP switch uplinks, the PVST+
BPDUs are dropped. A loop occurs.
C. Cisco distribution switches send untagged standard BPDUs to the HP switch in VLAN 1,
and in response the HP switch blocks one of the uplinks
on all VLANs, preventing a loop.
D. Cisco distribution switches send untagged standard BPDUs to HP switch in VLAN 1,
which the HP switch forwards to the other distribution
switch, preventing a loop. The HP switch drops all tagged data frames.
Answer: D
A company's LAN is composed of Cisco switches only. The network runs Rapid PVST+
with the short pathcost method. Cisco distribution switches are set as root and secondary
root in all VLANs. These two switches connect over an Etherchannel. The company wants
to install HP PoE switches at the edge of its LAN. The customer wants to keep the load-
balancing of traffic that is set in PVST+. What are the possible options? (Select three.)
A. ensure Spanning Tree is disabled on the HP edge switch, and configure loop-protection
on edge ports to avoid local loops
B. if the HP edge switch is an A-Series switch, configure Smart Link with load balancing
between instances
C. if the HP edge switch is an A-Series switch, configure Rapid PVST+ on it
D. configure MSTP on the HP edge switch, but set the cost of its uplink higher than that on
the channel between the distribution switches
E. configure MSTP on the HP edge switch and divide the VLANs into different instances
F. configure MSTP on the HP edge switch and set its uplink port cost to 5
G. configure MSTP on the HP edge switch, but set the cost of its uplink lower than that on
